#! /bin/sh# This script accepts any number of file arguments and checks them into RCS.## Arguments which are detectably either RCS masters (with names ending in ,v)# or Emacs version files (with names of the form foo.~<number>~) are ignored.# For each file foo, the script looks for Emacs version files related to it.# These files are checked in as deltas, oldest first, so that the contents of# the file itself becomes the latest revision in the master.## The first line of each file is used as its description text. The file itself# is not deleted, as under VC with vc-keep-workfiles at its default of t, but# all the version files are.## If an argument file is already version-controlled under RCS, any version # files are added to the list of deltas and deleted, and then the workfile# is checked in again as the latest version. This is probably not quite# what was wanted, and is the main reason VC doesn't simply call this to# do checkins.## This script is intended to be used to convert files with an old-Emacs-style# version history for use with VC (the Emacs 19 version-control interface),# which likes to use RCS as its back end. It was written by Paul Eggert# and revised/documented for use with VC by Eric S. Raymond, Mar 19 1993.case$# in
